The target of the workshops held at the side of ER 2002, the twenty first overseas convention on Conceptual Modeling, used to be to offer individuals the opportunitytopresentanddiscussemerginghottopics,thusaddingnewpersp- tives to conceptual modeling. to satisfy this target, we chosen the next 4 workshops: – 2d InternationalWorkshop on Evolution and Changein information administration (ECDM 2002) – ER/IFIP8. 1 Workshop on Conceptual Modelling techniques to cellular - formation platforms improvement (MobIMod 2002) – foreign Workshop on Conceptual Modeling caliber (IWCMQ 2002) – third foreign Joint Workshop on Conceptual Modeling methods for E-business: an online carrier point of view (eCOMO 2002) ER 2002 used to be geared up in order that there will be no overlap among the c- ference classes and the workshops. This court cases includes workshop papers that wererevisedby the authors following discussions throughout the convention. we're deeply indebted to the contributors of the organizing committees and application committees of those workshops for his or her exertions.

This publication offers revised complete models of the simplest papers approved for the SCM-4 and SCM-5 Workshops on software program Configuration administration, held in reference to the 1994 and 1995 IEEE overseas convention on software program Engineering (ICSE). The 22 papers incorporated supply a distinct evaluate on and creation to present software program configuration administration concerns.

This e-book constitutes the completely refereed post-proceedings of the 3rd foreign Workshop on Formal facets in safety and belief, quick 2005, held in Newcastle upon Tyne, united kingdom in July 2005. The 17 revised papers offered including the prolonged summary of one invited paper have been rigorously reviewed and chosen from 37 submissions.

AgentId AND VALID(T1) OVERLAPS VALID(T)) Through this query, by using the default semantics of TSQL2 in the FROM clause, tuples of tables AgentAvailability, TaskHistory, and Agent are associated only if their valid times intersect (in this case, tuples of atemporal tables are considered as always valid); the condition expressed in the WHERE clause is then evaluated on these tuples. Valid times of tuples in the result are the intersection of the tuples considered in the evaluation of the query. Process Model Designer Tool: The process model engineer uses a tool, namely workﬂow designer, to formally deﬁne the schema inside the WfMS.
